Abstract

A process for the production of unsaturated esters and alcohols comprises reacting an ester of formula: <FORM:0952973/C2/1> where X is a carboxylic acid ester radical, R1 a hydrogen atom or a p- or sec alkyl or alkenyl radical, and R2 a p- or secalkyl or alkenyl radical or phenyl radical, with an aliphatic or cycloaliphatic olefinically unsaturated compound which may be an olefine or an olefine substituted by an ester, ether or hydroxy group in the presence of a Friedel Crafts catalyst. R1 may be methyl-, ethyl-, propyl, propenyl- and 4-methyl-pent -3-enyl-radical and 4, 8-dimethyl-nona-3.7 dienyl, and the ester radical may be acetate, propionate, butyrate or benzoate and esters mentioned are a , a -di methylallyl (prenyl) acetate, crotyl acetate or cinnamyl acetate. The olefines and substituted olefines may be isobutene, styrene, a -methylstyrene, anethol, isosafrol, limonene, cyclohexane, propylene, isoprene and butadiene, or compounds of the formula of the first component such as, g g-dimethallyl, methallyl, 2-methyl-but-1-ene, isopentenyl and geranyl acetates. Orthophosphoric, pyrophosphoric, dichloracetic, perchloric, sulphuric, boron trifluofride, zinc chloride or toluene sulphonic acids are mentioned as suitable cataysts and the process may be in inert solvent such as acetic acid esters. Examples describe the reaction of isobutylene with g , g -dimethylallyl (prenyl) acetate to form 2, 6dimethyl-hept -2- enyl-acetate together with higher boiling constituents; anhydrous g , g dimethallyl acetate with itselt, alone or in ethyl acetate diluent, to form oxydihydrolavandulydiacetate, lavandulyl acetate, and higher boiling point constituents; g , g 2-dimethallyl propionate with itself to form lavandulyl propionate, oxydihydro-lavandulyl dipropionate and a higher boiling residue; 2-methyl-but-1-ene-4- acetate with g , g -dimethallyl acetate to form terpene acetate (lavandulyl, alto- and iso-geranyl and neryl acetates), 2, 6-dimethyl oct-2- ene-6, 8-diol-diacetate and sesquiterpene acetate with higher boiling fractions; isopentenyl acetate and prenyl acetate in ethyl acetate or acetic acid to yield terpene acetate, geraniol-hydrate-diacetate and higher boiling point fractions; isopentenyl acetate and g g -dimethylallyl acetate with a pyrophosphonic acid catalyst (followed by) the saponification of the ester to form terpene alcohol (lavandulol, a C10 alcohol, iso-and altogeraniol, nerol, and geraniol); isopentenyl benzoate in ethl acetate followed by saponification to lavandulol, alto- and isogreraniol, nerol, and geranol; 2, 6-dimethylocta-2, 6-dien -8- ol (geranyl) acetate with isopentenyl acetate followed by saponification to fornesol; isopentenyl acetate and prenyl acetate to form terpene acetate, geraniol-hyrate, di-acetate and higher boiling components.
